It is impossible to overstate the significance of the crude oil hub in Patoka, IL, to refineries in the Midwest. The seven-terminal hub, whose 80-plus above-ground tanks can hold more than 17 million barrels of crude oil, serves as the primary storage, blending, and staging site for a dozen refineries in five states with a combined capacity of more than 2.6 MMb/d. In other words, if the folks that keep Patoka running decide to take a couple of days off, Midwest refining would pretty much grind to a halt. And that’s not all: the southern Illinois hub also plays a critical role in sending crude oil south to the Gulf Coast. Today, we conclude our series on the Patoka hub with a look at the infrastructure within the facility’s boundaries and the pipes that transport oil out of it.
